This is Colossal:
The National Aeronautics and Space Administration (NASA) has created a library of 140,000 high definition files filled with photos, videos, and sound clips, all free and available for download. Visual and audio content of planets, moons, nebulas, and specific space missions, are searchable by file type. The library spans the last hundred years, and users can narrow searches to focus on any timeframe between 1920 and 2019. Each file also contains a thorough caption including the date and contextual information about the content.
What an amazing library to peruse.
